LP396x 800-mA Fast Ultra-Low-Dropout Linear Regulators  
1 Features  
3 Description  
The LP396x series of fast ultra-low-dropout linear  
1
Input Supply Voltage: 2.5 V to 7 V  
Ultra-Low Dropout Voltage  
regulators operate from a 2.5-V to 7-V input supply. A  
wide range of preset output voltage options are  
available. These ultra-low dropout linear regulators  
respond very fast to step changes in load which  
makes them suitable for low-voltage microprocessor  
applications. The LP3961 and LP3964 are developed  
on a CMOS process which allows low quiescent  
current operation independent of output load current,  
as well as operation under extremely low dropout  
conditions.  
Low Ground Pin Current  
Load Regulation of 0.02%  
15-µA Quiescent Current in Shutdown Mode  
Specified Output Current of 0.8-A DC  
Output Voltage Accuracy ±1.5%  
ERROR Flag Indicates Output Status (LP3961)  
Sense Option Improves Better Load Regulation  
(LP3964)  
Dropout Voltage: Ultra-low dropout voltage; typically  
24 mV at 80-mA load current and 240 mV at 800-mA  
load current.  
Extremely Low Output Capacitor Requirements  
Overtemperature and Overcurrent Protection  
40°C to 125°C Junction Temperature Range  
Ground Pin Current: Typically 4 mA at 800-mA load  
current.  
ERROR Flag: ERROR flag goes low when the output  
voltage drops 10% below nominal value (for LP3961).  
2 Applications  
Microprocessor Power Supplies  
GTL, GTL+, BTL, and SSTL Bus Terminators  
Power Supplies for DSPs  
SCSI Terminator  
SENSE: SENSE pin improves regulation at remote  
loads (for LP3964).  
Precision Output Voltage: Multiple output voltage  
options are available ranging from 1.2 V to 5 V and  
adjustable (LP3964), with a specified accuracy of  
±1.5% at room temperature, and ±3% over all  
conditions (varying line, load, and temperature).
